tends into enlarged portions 59 and 60 at its ends and has attached toone end a gear 6| covered by a plate 62. The member 58 with the bore 63is rotatably arranged on the post 55 and held in place by means of ascrew 64 engaging the groove 51.

A substantially circular housing l65 is secured to the enlarged upperend 60 as yby screws 66 and by the' screws 64 to'the enlarged lowerportion 59 and has attached close to one edge thereof a verticallyextending angular member 61. To

the other edge is hinged as at; 6,8 al radialmem- A ber 69.

A cam member 10 is pivoted at 1| in the enlarged lower end 59 and at 12inthe enlarged upper end 60, and has a level` 'E3 attached there- Bymeans of the lever '|3,;thecammember 4 22 and particularly to Figures l,2, 10, 1l and 12, a square post |99 is provided with a base withapproximately the width of the rectangular area |68 to allow a slidingmovement of the post |09.

At the top the post |99 has secured thereto a bar |Il9a, to slidablyaccommodate a U-shaped cross member having downward extensions IIZ'and||3 and extending into arms ||4 and I |5. The arm I4 is provided with adownwardly extending shaft H6, accommodating sleeves ||1 `and ||3towhich are secured springs I |9, the latter to engage the core 35 ofthe roll 36, when inserted into the top of the roll.

The arm H5 extends into a yoke |20 to en- 'gage a roller |2| looselymounted on the extenmay be brought into engagement with the radialmember 69. x

A vertically extendiny cam 14 is pivoted to the lower end 59 as shown at15 and to the upper end 60 as at 16 and has secured thereto a lever 11,by means of which the cam 'I4 may be brought into engagement with theopen end of the housing 65.

A shaft 18 is iournaled at its lower end in the platform 52 and carriesa gear 'I9 tomesh with the gear 6| of the tubular member 58. At itsupper end the shaft 18 passes through an arm 80 formed in the frame 54and carries a bevel gear 8|, to mesh with awbevel gear 82 connected onAa shaft 83 and rotatably arranged in the bearing 34 formed on the frame54. `A'set screw 65 is provided in the bearing 84 to lock the gears inany desired position, as may be seen from Figure '1.

A crank handle 89 is secured to the shaft 83, by means of which thebevel gears 8| 'and 82 and the gears 'I9 and 6| may be turned, thusrotating the tubular member 58 with all its connecting parts. f

A U-shaped handle 81-is connected to the framel 54 as at 88 to allow foreasy manipulation to and from any of the display units 20 to which thedispensing unitj2| is to be connected, the operation of which will bedescribed later.

The Ygear 6| is covered by a-guard 89, while the rest of the mechanismis enclosed by the back 90 attached to the frame 54and bythe housing 9|,which at the top 92 has a block 93 attached thereto, to provide abearing for. the slidable rod 94. arc-shaped member 95 provided with alining 96. The rod 94,1,nay be locked` in `any-position ,by means of aset screw 91. as shown invFigures l, 2and7.

Pawls 98 are secured to the platform 52 `at 99 and normally held in adownwardiposition by springs |00. (See Figures -l and 2.) The pawls 98terminate into hook portions |0| to engage the notches 5| intheextensions v49 of the base andare held in such an engagement'bythe:

springs |00. These pawls 98 may be released from the notches 5| by meansof cam portions |02 provided on a shaft I 63, which latter is journaledto the platform 5,2 as at |04 and terminates into a handle |05.

The pawls98 come into locking position with Referring now to thefcuttingmechanism.

To thelatter is connected an sion |22 of the tubular member 58, theroller |2| being held in place by a bolt |23 and a washer |24. Theroller |2| may be locked into the yoke by a latch |25 secured to the arm||5 as at |26.

Thus it will now clearly be understood from the foregoing descriptionthat by the insertion of thesprings ||9 into the core 35 of roll 36e-ndthe engagement of the base l0 within the space |08, the cuttingI unit 22is thus brought in proper relation with the roll 36 and held in this=rela= tion by the latch member |25.

A bar |21 is slidably arranged in relation to the post |09 by means ofrods |28 and secured by nuts |29 thus forming an openingY |30 throughwhich the end |3| of theroll 36 maybe passed. Between the post |09 andthe bar |21 are interposed springs |32 to normally keep the opening |30in an open position. The other ends of rods |28r are pivoted at |33;.tocam. members' |34, formed with projections, said cam members areconnected to rods |35 provided with reduced por' tions |36 slidable inrods |38 and surroundedrby tension springs |31, one end of which is con'nected to the rods |35. Theother ends of springs |31 are secured at` |39to the rods |38, which in turn are pivoted at |40 .to a'ratchet |4| on astud |42 rotatably mounted in a bracket |43 fast 'on thepost |09.v Thestud |42 also carries anarm |44 by means of which the ratchet may berotated and held in position by a pawl member. |45 pivoted at |45 to the.post |09. 1

Secured at itsupper and lower end of post|09 as shown at |41 and |48, isa bar |40 toac'commodate a;slide.| 50, providedwith rollers-'|51 toengage the bar 49. The slide is provided with a handle |52. A circularcutting knife |53 is-rotatably secured tothe slide |50 at |54 and'held'in a fixed position by ascrew |55 in the slide |50, entering into one ofthe holesl 56 of the knife |53.' Thus only part of the cutting-edge |51is in use at any time, as clearly shown in Figure 12, and if this partof the `knife |53 through extensive use-becomes worn, an unused sectionof the knifelmay be exposed by means of .the screw 655 and holes |56. Bythis arrangement theknife may be lused for a considerable length oftime, before a'removal forV resharpening or-'replacement becomesnecessary. f I

The post |09 is provided with extensions |58` having bayonet slots |59to accommodate a bracket |60 of a metering device |6|'. The 5mechanismof this device is not shown, but connected with it is a downwardlyextending shaft |62 jour# nailed in the bracketv |60. A gear |63 issecured` The shaft 65is `iournalle'd in a sleeve |68 pivot'ed"'Ijhe"slide'|50 'is frictionally'held in its upper ppsitionby-'faball-|13-engaginga depression; 14, jthe balll beingY kept inengagement with,ythe d e- ;p sion |14 bya'spring- |1-5jin a'nppening lili-'of post 0,9;thisopening beingf closed bya screw sliding'loiijthe bar |0hr by'meansofa screwv |18. vliiescribing now more' fully the operation oftheinvention, the springs I ||l-:of.fthe,cutting unit 22 are inserted intothe coreof the roll from which the, material is to be dispensed, thebasey |,l to biefplacedvhetween the, extensions 49 and` heldwithinthis'space by the forwardedge |06"of"the platform 52, which islocked in position with the display unit by means of pawls IOI, thelatch also having been locked to the roller-42| of the dispensing unit2|'. The end |3| of a roll"36, on the display unit 20 is fed between thefriction rollers |66 and |61 and through the opening |30 into thedispensing unit 2| and within the circular housing 95 until the edge ofthe end |3| position by means of the ca-m 10 and lever 13, asv

shown in dotted lines in Figure 8 and in full lines in Figure 9.

When the desired amount or length as indicated by the measuring devicehas been wound on the roll 65, the gear mechanism and the yoke 95 withthe lining 96 is then brought into engagel ment with the wound materialvand locked by the screw 91 to prevent unwinding of the material; 6|,19, 8| and 82 may then belocked by the screw 85. The bar |21 is thenbrought in close contact with the material |3| by means of the rods |28,cams |34, rods and |38, and the ratchet |4| and pawl I 45, thus holdingthe material clamped firmly within the slot |30. The slide with theknife |53 may then be moved downward on the guide bar |49 by means ofthe handle |52 and the knife |53 engaging the edge |8|lr of the post |09will then cut and separate the dispensed material from the materialstill left on the roll. The gears may then be unlocked and therem'aining end wound on the housing at which stage the wound material isthen ready for tieing by strings or any other suitable means.

To facilitate easy removal of the tied up roll, the member 69 is broughtback into its innermost position after the cam 14 has been released fromengagement with the material |3|. The dispensing device 2| may then bedisengaged from the display unit 22 and moved to any suitable place forthe removal of the roll. v
